High quality resin fallen tree stump aquarium hide that my fish and I absolutely love!
This aquarium corner, below substrate hide is super cute! My corydora catfish and shrimp have been absolutely loving the space. It is nice and dark which attracts my low light loving fish and provides a space for them away from their tank mates. This space in my aquarium is very popular and it looks like a natural log under the water. It’s made of a hard resin material which keeps it on the bottom of the tank and it’s safe to use in freshwater tanks. It was easy to put in the corner and set up, although it it’s not an exact corner angle and only allows one side to sit flush against the glass so sand was able to get in between. Overall this really elevated the beauty and functionality of my aquarium!

Betta’s Barky Bridge
This fish tunnel is extremely sturdy and looks very nice compared to the straight plastic-appearing ones! This tunnel is a great size and works well in my 10g tank, and my bettas love it! It blends into the decor a lot better than the plastic one I had before. This one is also heavy enough on it’s own that it does not need excessive substrate or gravel on it, which makes cleaning the surrounding substrate a lot easier without worrying about this tunnel becoming loose and floating away.

Good Quality, But Check the Tape Measure
This resin hideout is a product of good quality and feels like it will last for a long time in the tank. The texture genuinely mimics real rock without any rough edges that could scratch delicate fish, and it stays perfectly stable at the bottom of the aquarium, as advertised. My pleco and shrimp seem to enjoy having a new, safe spot to hide.However, the main issue, and the reason I give it 3 stars, is the size. Make sure to take note of the size measurements (5.1″L x 5.1″W x 2.8″H) and NOT go off of the pictures. The promotional images make it look way bigger than it really is.

Fair price and fish love it
Why I got it:I have two aquariums, and each with various small species fish and crustaceans which love to hide, but I’d love to still see.What I liked:That is a heavy suckered, in a good way, and it won’t be pushed over easily. The size is big enough for various aquatic life to live and hide in. No weird smells, no fish dead from any residual chemicals, the log look is pleasant with no visual errors in quality, and the bottom feeders seem to adore it right away. Even my panther crab moved from their favorite spot to burrow under it, and had made it their favorite spot since.What I didn’t like:Honestly? Nothing, I genuinely we a complaint about!Overall experience:With how expensive aquarium decore is these days. The price and quality beats things that are far more expensive yet worse in quality. It’s a good buy if you have soggy critters that love to hide. Just be sure, like any item being put in the aquarium, to wash them first. Preferably with treated aquarium water, or a mix of vinegar and water with very thorough rinse.

Feels solid but a bit too small
This product is solid in terms of its material, and doesnât seem cheaply made. In terms of the size, I think this would be good for smaller fish, like shrimps, crabs, maybe some tetras, but for betta fish, a bit on the smaller side. I think if you got this for a betta fish, itâll have to be a betta with smaller fins, or maybe a female. But, the product is good, seems sturdy enough

A corner cave! So unique and fun for the fish!
This is such a unique piece of aquarium decor. Decorating the corners of your tank can be tricky. Many different breeds of fish love caves. It’s a safe place to hide, or a curious area to explore. I have a community tank with a variety of species and they ALL love this corner cave. The betta, Cory dobras, mollies, guppies and shrimp explore this corner cave. When you place it in the front of your tank you get to see them swim through or hang out. If you want to offer your fish a more private, dark corner cave then you can have it face the rear wall of your tank. The color is great I like the log look. I highly recommend. It’s really neat to see my fish constantly swimming in and out of it. They clearly enjoy this decor.

The fish like it!
This corner decor is very sturdy and looks great. It does get a bit “lost” in my 55gallon, but the fish like it and that’s what matters most. I would say that for this size it would be PERFECT for a 10-20 gallon tank.Note: My tank was freshly set up and the new gravel made the water murky for a few hours. haha

Betta loves it
My betta loves this. He explored it for about 5 minutes before he figured out how to get inside and swim around. He does it all the time now as he makes his rounds in his tank. I try to keep food out of there just so it’s a little easier to clean, but it would probably be okay to drop some in there for your fish to find. So far I’m happy with this little cave.
